Concept explainers
(a)
Interpretation:
Smallest possible rectangular unit cell for layer of graphite has to be drawn.
Concept Introduction:
Graphite is hard carbon material that is example of network solids. It is also called allotrope of carbon. It means graphite forms in such ways that it differs in connectivity of atoms. Graphite forms in layer of carbon sheets and these sheets are known as graphene sheets.
(b)
Interpretation:
Number of carbon atoms in smallest possible rectangular unit cell in layer of graphite has to be determined.
Concept Introduction:
Refer to part (a).
(b)
Interpretation:
Coordination number for carbon atoms in smallest possible rectangular unit cell inlayer of graphite has to be determined.
Concept Introduction:
Refer to part (a).
